<span>Answer:
Let P be the proportion of correct results of all polygraph results
H0: P ≥ 0.80
Ha: P < 0.80
Estimated p = 74 / 98 = 0.7551
Variance of proportion = p*(1-p)/n
= 0.8(0.2)/98 =0.0016327
S.D. of p is sqrt[0.001633] = 0.0404
z = ( 0.7551 - 0.8 ) / 0.0404 = -1.1112
P-value = P( z < -1.1112) = 0.1335
Since the p-value is greater than 0.05, we do not reject the null hypothesis. Based on the results there is no evidence that polygraph test results should be prohibited as evidence in trials.</span>
According to the data tables and histogram, i can draw the conclusion that Table/Answer would be The first choice.
Hope this helps.
Answer:
3448.5
Step-by-step explanation:
I=PRT
I=22990×0.05×3
=$3448.5
For 4x^2y over 2x^8y^4 try 2 over x^6y^3
The values go up by 2. So your answer would be 20.
